The cache is two-way set associative with a least recently used (LRU) replacement policy. Both instruction and data accesses towards flash memory or XIP code regions are cached.
In Cache mode (MODE=Cache), instruction and data accesses from the CPU over the code bus towards internal or external flash, are cached. The contents of the cache, i.e. data, tag, valid, and MRU bits, are memory mapped, see Cache content. This can be used for performance profiling of code running in the system. Access to the cache content region is read-only by default, but can be blocked by enabling a lock bit in DEBUGLOCK. Preventing cache content updates on cache misses can be enabled through register DEBUGLOCK. When enabled, cache content is not replaced, but kept intact. The cache is still enabled and provides fast instruction and data fetches for cached content.
Access to internal or external flash memory will not be cached when in Ram mode (MODE=Ram). Instead, the cache data content, as described in Cache content, can be used as read/write RAM.
Cache information is divided into cache info content and cache data content.
The cache info and cache data content are memory mapped in the CACHEINFO and CACHEDATA regions. These can be accessed in the CACHEINFO registers and CACHEDATA registers respectively.
The cache includes profiling counters IHIT, IMISS, DHIT, and DMISS for both flash and execute-in-place (XIP).
Cache performance on executed code is indicated by these counters when enabled through PROFILINGENABLE. The counters can be cleared at any time using PROFILINGCLEAR. Writing to this register will clear all profiling counters. After being cleared, the counters will increment at the next instruction, or data fetch, according to the rules in the following table.
Profiling counter | Description |
---|---|
IHIT | Increased on a cache hit for instruction fetch |
IMISS | Increased on a cache miss for instruction fetch |
DHIT | Increased on a cache hit for data fetch (i.e. LOAD type instruction targeting the cache region) |
DMISS | Increased on a cache miss for data fetch (i.e. LOAD type instruction targeting the cache region) |
